CAN-OPENER.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed. January 2'7, 1919. Serial No. 273,338.

To all whom it may concern:

Be it known that I, PATRICK MULLANE, a citizen of the United States, residing atEast Moline, in the county of Rock Island and tiitate of Illinois have invented a new and useful Can-Opener, of which the following is a specification.

This invention relates to can openers, one of its objects being to provide a device which will be forced readily into the end of the can so as to produce a segmental out wherethe can can be opened readily and quickly.

A. further object to provide a cutting blade of novel form which is so shaped as to produce a small initial perforation and subsequently shear into the can, thus reducing to the minimum the force necessary to be erted when opening a can.

With the foregoing and other objects in view which will appear as the description proceeds the invention consists of certain novel details of construction and combinations of parts which will hereafter be more fully described and pointed out in the claims it being understood that various changes may be made in the construction and arrangement of the parts, without departing from the spirit or sacrificing any of the ad vantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings:

lFigure 1 is a side elevation of the can opener, the can to Which it is applied being indicated by dotted lines.

Fig. 9. is a plan view.

Fig. 3 is section on line 8-8 Fig. 1.

Referring to the figures by characters of reference 1 designates a segmental top plate from the curved edge of which depends an arm 52 one having a laterally extending handle 3 at its lower end while curved side wings l project from opposite edges of the arm. An opening 5 is formed in the top plate 1 and secured. to the said top plate is a bowed blade 6 which extends across the arm 2 and has oppositely disposed cutting edges 7 and 8 curved downwardly and extending to the lower and upper end portions respectively of a shoulder 9. A perforating point 10 extends from the lower end of the shoulder 9 and beyond the cutting edge 8., Blade 6 may be attached to the top plate 1 in any manner desired as by means of rivets 11 extending through ears 12 projecting inwardly from the upper corners of the blade.

In using the device the plate 1 is positioned over the top of the can 0, with the arm 2 bearing against the side of the can and the point 10 resting on the can. The tool is then pushed downwardly. This will cause the point 10 to perforate the end of the can close to the wall or side of the can and con tinued pressure will cause the edge 8 to gradually move into the can until it has penetrated a distance equal to the length of shoulder 9. The edge 7 will then come into action and begin to shear the two edges cooperating to produce a wedging action whereby the cut into end of the can is made quickly and accurately. The cutting of the can can be facilitated by inserting a finger through the opening 5 and pressing downwardly on the can top so as to hold the cut portion of the top away from the cutting blade. During the cutting action the wings 4 as well as the arm 2 will act as guides to prevent the tool from turning or swinging out of proper position. I

What is claimed is:

1. A can opener including a top plate, a bowed blade secured thereto and depending therefrom, said :lolade having a shoulder provided at its lower end with a perforating point, there being curved oppositely extending cutting edges upon the blade and extending downwardly to the upper and lower ends respectively of the shoulder.

2. In can opener including an arcuate blade, a perforating point at the lower end of the blade, a shoulder extending upwardly from the point, an arcuate edge extending upwardly from the lower end of the shoulder and above the point to one side of the blade and another arc-mate edge extending from the upper end of the shoulder to the other side of the blade, said edges diverging upwardly.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.

PATRICK MULLANE.
